Features FAILSAFE receiver, RO = HIGH for: OPEN inputs Terminated inputs SHORTED inputs Compatible with popular interface standards: TIA/EIA-485 (RS-485) TIA/EIA-422-A (RS-422-A) CCITT Recommendation V.11 Bi-Directional Transceiver Designed for multipoint transmission Separate driver input, driver enable, receiver enable, and receiver output for maximum flexibility Wide bus common mode range (-7V to +12V) Pin compatible with: DS75176B, DS96176, DS3695 and SN75176A and B Available in SOIC package Description The DS36276 FAILSAFE Multipoint Transceiver is designed for use on bi-directional differential busses. It is compatible with existing TIA/EIA-485 transceivers, however, it offers an additional feature not supported by standard transceivers. The FAILSAFE feature guarantees the receiver output to a known state when the Interface is in the following conditions: Floating Line, Idle Line (no active drivers), and Line Fault conditions (open or short). The receiver output is in a HIGH state for the following conditions: OPEN Inputs, Terminated Inputs (50 Ohm), and SHORTED Inputs. FAILSAFE is a highly desirable feature when the transceivers are used with Asynchronous Controllers such as UARTs.
